A look back at transfer deadline day

So, another January transfer deadline day has come and gone - and as usual, it saw a lot of expenditure by ambitious clubs and more than a few surprises. Premier League clubs spent £60m, the second-highest amount shelled out by the top flight on this deadline day after the £135m in 2011. This begs the question: what were the most eye-opening developments this time around?

The more things change...

Watford striker Odion Ighalo made the leap to Chinese Super League club Changchun Yatai. £20m changed hands for the 27-year-old Nigerian, who has scored 16 Premier League goals during Watford's current stint in the top tier. Meanwhile, Burnley broke its club record in transfer fees as it picked up Norwich City midfielder Robbie Brady, 25, for a fee of potentially up to £13m.

Napoli forward Manolo Gabbiadini, 25, joined Southampton for a fee around £14m. "One of my dreams was to perform in one of the biggest leagues in the world, so now that it's happening I can't wait to start playing," Gabbiadini told BBC Sport. Another side now stronger in attack is Swansea City, which agreed to pay up to £5m for Aston Villa striker Jordan Ayew.

As part of that deal, Wales defender Neil Taylor went in the opposite direction. While Villa strengthened its Championship rearguard, Crystal Palace did the same in the league above as it captured Liverpool centre-back Mamadou Sakho on loan. Midfielder Luka Milivojevic also joined Palace - the Croatia international had previously been with Greek club Olympiakos.

...the more they stay the same

However, the day was also interesting for what didn't happen. While Chelsea were reportedly interested in taking goalkeeper Craig Gordon and striker Moussa Dembele off Celtic's hands, the two ultimately remained with the Scottish champions.

Dembele himself scotched speculation that we was on his way to the Blues, tweeting photos of Leonardo DiCaprio delivering his "I'm not leaving" speech in The Wolf of Wall Street and himself with his own arms similarly outstretched. He probably couldn't have put paid to that rumour in a better way.

Like their battle against relegation, Sunderland showed little promise on deadline day, failing to land Southampton forward Jay Rodriguez despite a £12m bid. The Black Cats had already missed out on signing striker Leonardo Ulloa from Leicester City.

There was much spending outside the Premier League, too

Championship clubs weren't far behind their Premier League counterparts in terms of deadline-day spending. £40m was collectively spent in the second tier, beating the previous record. For a fee that could touch £12m, Aston Villa took Brentford striker Scott Hogan.

Impressive in a different way was Wigan's signing of eight players on the same day. Winger Yanic Wildschut was offloaded to Norwich in a £7m deal. However, arriving at the DW Stadium were (deep breath) Grimsby striker Omar Bogle, Rangers keeper Matt Gilks, Eastleigh forward Mikael Mandron, Manchester City's Jack Byrne, Hartlepool midfielder Josh Laurent, French winger Gabriel Obertan and - on loan - Hull City's Alex Bruce and James Weir.

In a historic move, Matty Taylor left Bristol Rovers for Bristol City - the first player to cross that divide since 1987. That year, then US President Ronald Reagan delivered his "Tear down this wall" speech in relation to the then still-standing Berlin Wall - how ironic given recent events...
